CTEST_PARALLEL_LEVELΒΆ

This is a CMake Environment Variable. Its initial value is taken from the calling process environment.

Specify the number of tests for CTest to run in parallel. For example, if CTEST_PARALLEL_LEVEL is set to 8, CTest will run up to 8 tests concurrently as if ctest were invoked with the --parallel 8 option.

See ctest(1) for more information on parallel test execution.
